Thus, the screen refresh rate adjustment module may refresh and display the picture frames based on the target refresh rate.

The process of rendering a picture frame to display is described below.

First, some noun concepts involved in rendering to sending a picture frame in the embodiments of the present application are described.

1. Screen refresh rate (refresh rate): the refresh rate of the display screen of the electronic device is generally related to a fixed parameter of the display screen, and is a fixed value.

In the embodiment of the application, the electronic device can support a plurality of selectable screen refresh rates, and at least the lowest screen refresh rate and the highest screen refresh rate can be contained in the plurality of selectable screen refresh rates.

Alternatively, the plurality of selectable screen refresh rates may have only two selectable screen refresh rates, one being the highest screen refresh rate and one being the lowest screen refresh rate. Exemplary: two selectable screen refresh rates are: 60Hz,90Hz. Wherein 60Hz is the lowest screen refresh rate of the plurality of selectable screen refresh rates, and 90Hz is the highest screen refresh rate of the plurality of selectable screen refresh rates.

Optionally, the plurality of selectable screen refresh rates may also include more selectable screen refresh rates. Illustratively, 3 selectable screen refresh rates are included: 60Hz,90Hz,120Hz. Wherein 60Hz is the lowest screen refresh rate of the plurality of selectable screen refresh rates and 120Hz is the highest screen refresh rate of the plurality of selectable screen refresh rates.

Optionally, the plurality of selectable screen refresh rates may also include more selectable screen refresh rates. Illustratively, 4 selectable screen refresh rates are included: 60Hz,90Hz,120Hz,144Hz. Wherein 60Hz is the lowest screen refresh rate of the plurality of selectable screen refresh rates, and 120Hz is the highest screen refresh rate of the plurality of selectable screen refresh rates.

Optionally, the plurality of selectable screen refresh rates may also include more selectable screen refresh rates. Exemplary, 5 selectable screen refresh rates are included: 45Hz, 60Hz,90Hz,120Hz,240Hz. Wherein 45Hz is the lowest screen refresh rate of the plurality of selectable screen refresh rates, and 240Hz is the highest screen refresh rate of the plurality of selectable screen refresh rates.

It will be appreciated that the plurality of selectable screen refresh rates may also include more screen refresh rates, depending on the actual requirements. There may be many more options for alternative screen refresh rates, not limited herein.

2. Render frame rate (frame): the rendering thread representing the application invokes the GPU to render the frame number of the picture frame in 1 second. The rendering frame rate may be controlled by the application, the rendering frame rate being in PFS.

Wherein the maximum value of the rendering frame rate is the screen refresh rate.

The rendering frame rate determines how fast the rendering thread of the application invokes the GPU to render the picture frames. For example, when the rendering frame rate is 60PFS, the rendering thread of the application calls the GPU to render for an average of 16.7ms to obtain a frame of picture frame. For example, when the rendering frame rate is 90PFS, the rendering thread of the application calls the GPU to render for an average of 11.1ms to obtain a frame of picture frame. For example, when the rendering frame rate is 120PFS, the rendering thread of the application calls the GPU to render for an average of 8.3ms to obtain a frame of picture frame.

The higher the rendering frame rate, the faster the rendering thread of the application invokes the GPU to render the picture frame.

3. Vertical synchronization (vsync) signal: after the application needs to call the GPU to render the picture frames, the rendered picture frames can be stored in a layer buffer (buffer) and provided to a layer synthesizer (surface eFlinger) for layer synthesis. And after the surface eFlinger takes out the rendered picture frames from the buffer to carry out picture layer combination, sending the picture frames after the picture layer combination to a display screen to refresh and display. When the timing of sending the picture frames after the graphics layer is combined into the display screen is in the process of refreshing the screen, the phenomenon that two different picture frames before and after the graphics layer are overlapped and displayed easily occurs, so that the picture displayed by the display screen is torn (tearing). Therefore, in order to prevent such a phenomenon of picture tearing, the hardware module corresponding to the display screen may generate a vsync signal having the same period as the refresh rate to the surfeflinger. After the surface eFlinger receives the vsync signal, the surface eFlinger can take out the picture frame from the buffer to perform layer composition and send the picture frame to the display screen to refresh and display.

Fig. 2 shows a timing diagram of a picture frame provided in an embodiment of the present application from rendering to sending.

As shown in fig. 2, an application (e.g., a gaming application) may issue a rendering instruction to the GPU to render a frame of a picture, and after issuing the rendering instruction, the application may issue a frame-sending instruction for the frame of the picture to the SurfaceFlinger. After the GPU has rendered the frame, the GPU may store the frame into a buffer indicated by the rendering instruction. After the SurfaceFlinger acquires the frame sending instruction, the buffer of the picture frame can be acquired, after the SurfaceFlinger detects that the buffer of the picture frame is filled with the rendered picture frame, the picture frame can be taken out from the buffer of the picture frame to carry out layer synthesis when the next vsync signal arrives, and the picture frame is sent to the display screen to carry out refreshing display.

For example, between vertical synchronization signal 0 (VSYNC 0) and vertical synchronization signal 1 (VSYNC 1), the application may issue rendering instruction A to the GPU and frame instruction A to the SurfaceFlinger. After the GPU acquires the rendering instruction a, the GPU may render the picture frame a, and store the rendered picture frame a into the buffer of the picture frame a indicated by the rendering instruction a. The surface eFlinger can acquire a buffer of the picture frame A through the frame sending instruction A, and after the rendered picture frame A is filled in the buffer of the picture frame A, when the VSYNC1 arrives, the picture frame A is taken out from the buffer of the picture frame A to carry out layer synthesis, and the picture frame A is sent to a display screen to carry out refreshing display.

Between vertical synchronization signal 1 (VSYNC 1) and vertical synchronization signal 2 (VSYNC 2), the application may issue rendering instruction B to the GPU and frame instruction B to the SurfaceFlinger. After the GPU acquires the rendering instruction B, the GPU may render the picture frame B, and store the rendered picture frame B into the buffer of the picture frame B indicated by the rendering instruction B. The surface eFlinger can acquire the buffer of the picture frame B through the frame sending instruction B, and after the rendered picture frame B is filled in the buffer of the picture frame B, the picture frame B can be taken out from the buffer of the picture frame B to carry out layer synthesis when VSYNC2 arrives, and the picture frame B is sent to a display screen to carry out refreshing display.

Between vertical synchronization signal 2 (VSYNC 2) and vertical synchronization signal 3 (VSYNC 3), the application may issue rendering instruction C to the GPU and frame instruction C to the SurfaceFlinger. After the GPU acquires the rendering instruction C, the GPU may render the frame C, and store the rendered frame C into the buffer of the frame C indicated by the rendering instruction C. The surface eFlinger can acquire the buffer of the picture frame C through the frame sending instruction C, and after the rendered picture frame C is filled in the buffer of the picture frame C, when the VSYNC3 arrives, the picture frame C is taken out from the buffer of the picture frame C to carry out layer synthesis, and the picture frame C is sent to the display screen to carry out refreshing display.

Between vertical synchronization signal 3 (VSYNC 3) and vertical synchronization signal 4 (VSYNC 4), the application may issue rendering instruction D to the GPU and frame instruction D to the SurfaceFlinger. After the GPU acquires the rendering instruction D, the GPU may render the frame D, and store the rendered frame D into the buffer of the frame D indicated by the rendering instruction D. After the buffer of the picture frame D is obtained through the frame sending command D, and after the rendered picture frame D is filled in the buffer of the picture frame D is detected, when the VSYNC4 arrives, the picture frame D is taken out from the buffer of the picture frame D to carry out layer synthesis, and the picture frame D is sent to a display screen to carry out refreshing display.

The method and the device are applied to game scenes, and in order to save the power consumption of the electronic device 100 and improve the game experience of a user, the electronic device can dynamically regulate and control the refresh rate of the electronic device 100.

The electronic device 100 may determine the refresh rate of the electronic device 100 in combination with a variety of factors. Factors include, but are not limited to, any one or more of the following: game mode, game information, game scene, rendered frame rate jittered scene, whether split screen game, etc.

Not limited to the above factors, the factors determining the refresh rate of the electronic device 100 may be other factors, and the present application is merely exemplified by the above factors.

First, a game scene is introduced.

Fig. 3A-3D show schematic diagrams of entering a game scene based on a first game application.

As shown in fig. 3A, the electronic device 100 may display a desktop in which a page with application icons is displayed, the page including a plurality of application icons (e.g., a setup application icon, an application marketplace application icon, a gallery application icon, a browser application icon, a first game application icon, a second application icon, etc.). Page indicators are also displayed below the application icons to indicate the positional relationship between the currently displayed page and other pages. A tray area is displayed below the page indicator. The tray area includes a plurality of tray icons, such as a camera application icon, an address book application icon, a phone application icon, and an information application icon. The tray area remains displayed while the page is switched. In some embodiments, the page may also include a plurality of application icons and page indicators, which may not be part of the page, but may exist alone, and the tray icon may also be optional, which is not limited in this embodiment.

The electronic device 100 may receive user input (e.g., a single click) on a telephony application icon, in response to which the electronic device 100 may load a game resource and display the user interface 340 shown in fig. 3B, the user interface 340 may include the text "in progress for loading.

After the game resources are loaded, the electronic device 100 may display the user interface shown in FIG. 3C. Fig. 3C is a user interface 320 for a game provided in an embodiment of the present application. The user interface 320 may be referred to as a game lobby interface.

A start game option may be included in the user interface 320, for example, the start game option may be a competitive reactance option or a rank match option in the user interface 320, or the like. The user may begin a game via the athletic reaction option or the ranking game option in the user interface 320 and the electronic device 100 may display a game play interface.

For example, as shown in fig. 3C, the electronic device 100 may receive an input operation (e.g., a single click) by a user for an athletic reaction option in the user interface 320, and in response to the input operation by the user, the electronic device 100 may display the user interface 330 shown in fig. 3D, and the user interface 330 may also be referred to as a game play interface. Included in the user interface 330 is a play exit option by which the user can end the game and display the user interface 320 shown in fig. 3C.

Next, how the above factors determine the refresh rate of the electronic device 100 will be described.

1. Adjusting screen refresh rate based on game scene

1. Categories of game scenes

The game scenes may include, but are not limited to, game loading scenes and game play scenes.

The game loading scene may refer to a scene before entering a game hall or in the game hall after the game application is started. In the game arcade, the user may select game characters, select game modes, team, match teammates, download resource packages, pick up props and skins, etc.

For example, the electronic device 100 may receive an input operation by a user for the first game application icon shown in fig. 3A and display the user interface 340 shown in fig. 3B, and the user interface 340 may be a game loading interface.

After the electronic device 100 acquires the game resource, the electronic device 100 may display the user interface 320 shown in fig. 3C, and the user interface 320 may be a game loading interface.

Thereafter, the electronic device 100 may receive an input operation of the user for the athletic reaction option or the ranking competition option in the user interface 320 to start a game and enter a game play, the electronic device 100 may display the user interface 330 illustrated in fig. 3D, and the user interface 330 may be a game play interface.

Wherein user interface 340 and user interface 320 may be game loading scenarios.

The user interface 330 may be a game play scenario.

It should be noted that, the game loading scene and the game playing scene may also be other interfaces, and the application is only illustrative of the game loading scene and the game playing scene, which is not limited in this application.

2. Identifying game scenes

(1) The game loading scene and the game play scene are identified based on the frame rate characteristic information.

The first gaming application may invoke the GPU to render the frame of the picture. The number of frames that the first gaming application invokes the GPU to render the frame of the picture in 1 second may be referred to as the rendering frame rate of the first gaming application.

Wherein the frame rate characteristic information includes, but is not limited to, one or more of the following: average frame rate, composite time standard deviation of picture frames.

First, the electronic device 100 may obtain a rendering frame rate of the first game application every second for n consecutive seconds, and calculate an average frame rate for n seconds.

When the first game application renders the picture frames, each frame of picture frame has a time stamp, and the time stamp is used for identifying the successful rendering time of the picture frame, and the time stamps of different picture frames are different.

The electronic device 100 may obtain the time stamps of the frames of m consecutive frames, and calculate the difference between the time stamps of the frames of two adjacent frames to obtain the synthesis time of each frame. For example, electronic device 100 may obtain a timestamp for picture frame a, a timestamp for picture frame B, and a timestamp for picture frame C. The electronic device 100 may calculate a difference between the timestamp of the frame a and the timestamp of the frame B to obtain a duration a, where the duration a is a composite time of the frame a. The electronic device 100 may calculate a difference between the timestamp of the frame B and the timestamp of the frame C to obtain a duration B, where the duration B is a composite time of the frame B. And so on, the electronic device 100 may obtain the composition time for each picture frame.

After the electronic device 100 acquires the synthesis time of each of the m-frame picture frames, the electronic device 100 may calculate the synthesis time standard deviation of the m-frame picture frames based on the synthesis time of each of the m-frame picture frames.

In the case where the average frame rate and the standard deviation of the synthesis time satisfy the preset conditions, the electronic device 100 may determine that the current scene is a game loading scene.

For example, when the electronic device 100 determines that the average frame rate is less than 10PFS and the standard deviation of the synthesis time is greater than 10ms, the electronic device 100 may determine that the current scene is a game loading scene.

In the case that the average frame rate and the standard deviation of the synthesis time satisfy the second preset condition, the electronic device 100 may determine that the current scene is a game play scene.

For example, when the electronic device 100 determines that the average frame rate is greater than 30PFS and the standard deviation of the synthesis time is less than 5ms, the electronic device 100 may determine that the current scene is a game play scene.

(2) The game loading scenario and the game play scenario are identified based on the DrawCall average number.

Where DrawCall is the CPU invoking the image application programming interface. When the first game application calls the GPU to render the picture frame, a large amount of image resources are required to be acquired through the CPU, and then the CPU can acquire the image resources in a DrawCall mode. The CPU obtains an image application programming interface (such as a DirectX interface or an OpenGL interface) through the DrawCall, obtains an image resource based on the image application programming interface, and sends the image resource to the GPU, so that the GPU can render a picture frame based on the image resource.

Fig. 4 shows a schematic diagram of a method for the electronic device 100 to obtain the DrawCall number.

As shown in fig. 4, the electronic device 100 includes a game awareness module, a graphics public library, and a screen refresh rate decision module.

The graphic public library provides an external interface for the first game application to call and render the picture frames, and the like.

S401, the game perception module calls a HOOK glDrawCall function.

S402, the graphic public library sends the DrawCall operation to the game perception module.

The game perception module may call the HOOK gldraw call function, and then, after each draw call operation performed by the first game application, the graphic public library may send each draw call operation to the game perception module, so that the game perception module may count the number of draw calls.

S403, the game perception module counts the number of DrawCall operations.

After the game perception module receives the DrawCall operation sent by the graphic public library, the game perception module can count the number of DrawCall and calculate the average number of DrawCall in a certain time. For example, the game awareness module may count the number of DrawCall operations within 1 s.

S404, the game perception module determines a game scene based on the DrawCall operation quantity.

Because in the game play scene, the complexity of the game scene is higher, the change of the image frames is faster, and the GPU needs to call a large amount of image resources to draw hero characters, particle effects, illumination effects and the like, which all need to rely on DrawCall operation, so that the number of DrawCall operations is greatly increased.

In a game loading scene, the GPU only needs to draw a loading bar and a small number of scenes, so that the image resources are small, and the number of DrawCall operations is relatively small.

The game awareness module may determine the game scenario based on the average number of DrawCall operations.

For example, the game awareness module may count the number of DrawCall operations within 1s and determine a game scenario based on the average DrawCall number. When the number of DrawCall operations within 1s is greater than a preset value, the game perception module can determine that the game is a game play scene. When the number of DrawCall operations within 1s is smaller than a preset value, the game perception module can determine that the scene is loaded for the game. For example, when the number of DrawCall operations within 1s is greater than 200, the game perception module may determine to be a game play scenario. When the number of DrawCall operations within 1s is less than 200, the game perception module may determine to load a scene for the game.

For another example, the game awareness module may count the number of draw call operations per second in a continuous period of time and determine a game scenario based on the number of draw call operations per second in a continuous period of time. When the number of DrawCall operations per second in a continuous period of time is greater than a preset value, the game perception module can determine that the game is a game play scene. When the number of DrawCall operations per second in a continuous period of time is smaller than a preset value, the game perception module can determine that a scene is loaded for the game. For example, the game perception module may determine to be a game play scenario when the number of DrawCall operations in 3 consecutive seconds per second is greater than 200. When the number of DrawCall operations in each second of 3 consecutive seconds is less than 200, the game perception module may determine to load the scene for the game.

S405, the game perception module sends the DrawCall operation quantity to the screen refresh rate decision module.

After the screen refresh rate decision module obtains the average DrawCall operation number, the screen refresh rate decision module can determine the game scene based on the average DrawCall operation number, and then determine the screen refresh rate.

(3) And identifying a game loading scene and a game playing scene based on the IO operation times.

During a game loading scenario, IO operations may rise significantly because the game needs to read a large amount of game resource data from a storage medium (e.g., memory or disk) and load it into memory for use by the game.

IO operation is significantly reduced during game play scenarios, because the resources needed during game play loading scenarios are loaded into memory, and only a small amount of resources need to be loaded into memory during game play scenarios.

The electronic device 100 may identify a game loading scenario and a game play scenario based on the IO operation number.

When the number of IO operations within a certain period of time is greater than a preset value, the electronic device 100 may determine that the current scene is a game loading scene.

For example, when the number of IO operations or the IO operation frequency in a certain period of time is greater than 80% of the preset value, the electronic device 100 may determine that the current scene is a game loading scene.

When the number of IO operations within a certain period of time is smaller than a preset value, the electronic device 100 may determine that the current scene is a game loading scene.

For example, when the number of IO operations or the IO operation frequency in a certain period of time is less than 80% of the preset value, the electronic device 100 may determine that the current scene is a game loading scene.

The electronic device 100 may determine the game loading scenario and the game play scenario based on any one or several of the above. The electronic device 100 may also determine the game loading scenario and the game play scenario in combination with other methods, which is not limited in this application.

3. Adjusting refresh rate based on game scene

The electronic device 100 refreshes the display frames based on a default refresh rate (e.g., a first refresh rate).

When the electronic device 100 determines that the game is loaded, the electronic device 100 may decrease the refresh rate, e.g., adjust the refresh rate of the electronic device 100 from a first refresh rate to a second refresh rate, the second refresh rate being less than the first refresh rate. Thus, in a game loading scenario, where user requirements for image quality are not high, the electronic device 100 may reduce the refresh rate to save power consumption of the electronic device 100.

For example, when the electronic device 100 determines a game loading scenario, the electronic device 100 may set the refresh rate of the electronic device 100 to 30hz. Correspondingly, the rendering frame rate of the first game application also decreases, and the rendering frame rate of the first game application decreases to 30PFS or less.

When the electronic device 100 determines that the game is played, the electronic device 100 may increase the refresh rate, so that the picture is smoother, and the game experience of the user is improved. For example, the refresh rate of the electronic device 100 is adjusted from the second refresh rate to a third refresh rate, the third refresh rate being greater than the second refresh rate.

In some embodiments, the first gaming application may receive a user set frame rate of the game play scene, which may be referred to as a set frame rate.

In some embodiments, the first gaming application may report the set frame rate to the system, and upon determining to enter the game play scene, the electronic device 100 may adjust the refresh rate based on the set frame rate such that the value of the refresh rate is not less than the value of the frame rate and such that the refresh rate matches the frame rate.

For example, when the electronic device 100 obtains that the set frame rate reported by the first game application is 120PFS, the third refresh rate may be 120hz or more.

In other embodiments, the first gaming application may not report the set frame rate to the system, and the electronic device 100 may not be able to adjust the refresh rate based on the set frame rate. But the electronic device 100 needs to match the adjusted refresh rate to the set frame rate. Specifically, after determining to enter a game play scene, the electronic device 100 adjusts the refresh rate to a maximum value, so that the frame rate can reach the set frame rate. After a certain period of time, the frame rate stabilizes around the set frame rate, at which time the electronic device 100 may obtain the set frame rate based on the frame rate information, and then adjust the refresh rate based on the set frame rate, so that the value of the refresh rate is not lower than the value of the frame rate, and so that the refresh rate matches the frame rate.

For example, when the electronic device 100 may acquire the set frame rate of 120PFS based on the frame rate information, the third refresh rate adjusted by the electronic device 100 may be 120hz or more.

2. Adjusting refresh rate based on rendering frame rate dithering scene

The rendering frame rate has a plurality of gear positions selectable, for example, 120PFS, 90PFS, 60PFS, and 30PFS.

Illustratively, in a game play scenario, the electronic device 100 renders and refreshes picture frames at a high frame rate and a high refresh rate. As shown in fig. 5A, the first game application renders and synthesizes the picture frames at a rendering frame rate of 120PFS, but the rendering frame rate of the first game application is unstable due to the excessively high load of the CPU, and is fixed back and forth, so that the situation of clamping or delaying the game picture occurs, and the game experience of the user is affected.

The electronic device 100 may decrease the rendering frame rate of the first gaming application such that the frame rate stabilizes.

1. Identifying frame rate jitter

The electronic device 100 can recognize whether the frame rate jitters or the frame rate is stable based on the frame rate characteristic information and the CPU load. The frame rate characteristic information includes, but is not limited to, an average frame rate and a composite time standard deviation of the picture frames.

(1) Average frame rate

The electronic device 100 may obtain a number of frame images and determine an average frame rate of the number of frame images based on a composition time of the number of frame images.

For example, the electronic device 100 may obtain 200 frames of frames, dividing the 200 frames of frames into two portions, each portion including 100 frames of frames.

As shown in fig. 5B, the electronic device 100 may divide 100 frames of a picture into the window 1 and divide another 100 frames of a picture into the window 2.

Then, the electronic device 100 divides the 100 frames in the window 1 into 5 small windows, each small window including 20 frames.

Similarly, the electronic device 100 divides the 100 frames in the window 2 into 5 portlets, each of which includes 20 frames.

The electronic device 100 may obtain the overall average frame rate for window 1 and window 2, as well as the average frame rate for each widget.

The electronic device 100 may obtain the total rendering time of the 200 frames, and divide the total rendering time of the 200 frames by 200 to obtain the average frame rate of the 200 frames.

The electronic device 100 may obtain the total rendering time of 20 frames in each of the windows 1 and 2, and divide the total rendering time of 20 frames in the window by 200 to obtain the average frame rate of 20 frames in each of the windows. For example, the electronic device 100 may obtain the total rendering time of 20 frames in the first widget in the window 1, and divide the total rendering time of 20 frames in the widget by 200 to obtain the average frame rate of 20 frames in the first widget in the window 1. For another example, the electronic device 100 may obtain the total rendering time of 20 frames in the second widget in the window 1, and divide the total rendering time of 20 frames in the widget by 200 to obtain the average frame rate of 20 frames in the second widget in the window 1. By analogy, the electronic device 100 may obtain the average frame rate of each widget, i.e., obtain the average frame rate of 10 widgets.

In some embodiments, if the electronic device 100 determines that the average frame rate of 200 frames and the average frame rate of every 20 frames meet the preset condition after determining that the average frame rate of 200 frames and the average frame rate of every 20 frames, the electronic device 100 may determine that the current frame rate is stable.

For example, if the difference between the average frame rate and the set frame rate of 200 frames is within the preset range, the current frame rate may be determined to be stable.

For example, if the frame rate is set to 60PFS, if the average frame rate of 200 frames is between 55PFS and 65PFS, the current frame rate can be considered stable. For another example, if the frame rate is set to 90PFS, if the average frame rate of 200 frames is between 80PFS and 100PFS, the current frame rate can be considered stable. For another example, if the frame rate is set to 120PFS, if the average frame rate of 200 frames is between 105PFS and 135PFS, the current frame rate can be considered stable.

In some embodiments, if the average frame rate of a certain number of small windows in the average frame rates of 10 small windows is within a preset range, the current frame rate may be determined to be stable.

For example, if the average frame rate of at least 8 small windows among the average frame rates of 10 small windows is within the preset range, the current frame rate may be determined to be stable.

For example, if the average frame rate of 200 frames is 80PFS and the average frame rate of at least 8 of the 10 windows is between 80.5PFS and 79.5PFS, the current frame rate may be considered stable.

The above-mentioned determination of whether the current frame rate is stable or not by the average frame rate of the frame in the large window and/or the average frame rate of the frame in the small window can more accurately reflect whether the frame rate is jittering, and the accuracy of the electronic device 100 in determining the frame rate jittering is improved.

(2) Standard deviation of synthesizing time of picture frame

When the first game application renders the picture frames, each frame of picture frame has a time stamp, and the time stamp is used for identifying the successful rendering time of the picture frame, and the time stamps of different picture frames are different. The electronic device 100 may obtain a time stamp of each frame of the 200 frames, and calculate a difference between time stamps of two adjacent frames to obtain a composite time of each frame. For example, the electronic device 100 may obtain a timestamp of a first frame of 200 frame frames, a timestamp of a second frame of 200 frame frames, and a timestamp of a third frame of 200 frame frames. The electronic device 100 may calculate a difference between the time stamps of the first frame of the 200 frame frames and the second frame of the 200 frame frames to obtain a duration 1, where the duration 1 is a synthesis time of the first frame of the 200 frame frames. The electronic device 100 may calculate a difference between the time stamps of the second frame of the 200 frame frames and the third frame of the 200 frame frames to obtain a duration 2, where the duration 2 is a synthesis time of the second frame of the 200 frame frames. By analogy, the electronic device 100 may obtain the composition time of each of the 200 frames.

After the electronic device 100 acquires the synthesis time of each of the 200 frame frames, the electronic device 100 may calculate the synthesis time standard deviation of the 200 frame frames based on the synthesis time of each frame.

If the standard deviation of the synthesis time of 200 frames meets the preset condition, the electronic device 100 may determine that the current frame rate is stable.

For example, when the electronic device 100 determines that the standard deviation of the synthesis time of 200 frames is less than 3ms, the electronic device 100 may determine that the current frame rate is stable.

It should be noted that the 200 frames and the 20 frames in each widget are only used to explain the present application, and may include other more or less frames, which is not limited in the present application.

(3) CPU load

The electronic device 100 may obtain a CPU load condition. If the CPU load is greater than the preset value, the electronic device 100 may determine the frame rate jitter. If the CPU load is smaller than the preset value, the electronic device 100 may determine that the frame rate is stable.

For example, if the electronic device 100 determines that the CPU load is greater than 85%, the electronic device 100 may determine that the frame rate is jittered. If the CPU load is less than 85%, the electronic device 100 may determine that the frame rate is stable.

The electronic device 100 may determine that the frame rate jitters or the frame rate is stable based on any one or a combination of the above. Not limited to the above manner, the electronic device 100 may also determine that the frame rate jitter or the frame rate is stable in combination with other manners, which is not limited in this application.

2. Adjusting refresh rate

After the electronic device 100 determines the frame rate jitter, the electronic device 100 may adjust the refresh rate. After the refresh rate is reduced, the frame rate of the electronic device 100 is also reduced, so as to avoid occurrence of frame rate jitter at a high frame rate.

The electronic device 100 may then monitor the frame rate condition for frame rate jitter or stability. If the frame rate is stable, the refresh rate does not need to be adjusted again, the picture frames are rendered at the adjusted frame rate, and the display picture frames are refreshed at the adjusted refresh rate.

If the frame rate is still jittered, the refresh rate needs to be reduced again, and after the refresh rate is reduced again, the frame rate of the electronic device 100 will also be reduced again, and the frame of the display frame is rendered at the readjusted frame rate, and the frame of the display frame is refreshed at the readjusted refresh rate.

In this way, the electronic device 100 may sequentially decrease the refresh rate of the electronic device 100 to decrease the frame rate, and the refresh rate of the electronic device 100 is not adjusted after the frame rate stabilizes.

For example, before the adjustment, the refresh rate of the electronic device 100 is 120hz, after recognizing the frame rate jitter, the electronic device 100 may reduce the refresh rate to 90hz, and the rendering frame rate of the corresponding first game application may also be reduced to 90PFS, as shown in fig. 5C.

The electronic device 100 may then monitor the frame rate condition for frame rate jitter or stability. If the frame rate is stable, the refresh rate does not need to be adjusted again, and the frame of the picture is rendered at the frame rate of 90PFS, as shown in FIG. 5C.

If the frame rate remains jittered, the electronic device 100 may need to decrease the refresh rate again to 60hz, and the corresponding rendering frame rate of the first game application may also decrease to 60PFS, as shown in fig. 5D. If the frame rate stabilizes at 60PFS, the electronic device 100 may not adjust the refresh rate. Otherwise, the electronic device 100 may continue to decrease the refresh rate until the frame rate stabilizes.

In some embodiments, if the frame rate is reduced by the refresh rate of the electronic device 100, the frame rate stabilizes after a period of time. The electronic device 100 may further increase the refresh rate so that the frame rate may be increased, so that the picture is smoother, and the game experience of the user is improved.

In one possible implementation, the electronic device 100 may gradually increase the refresh rate.

For example, after the electronic device 100 reduces the refresh rate to 60hz, the frame rate of the electronic device 100 has stabilized. The electronic device 100 may increase the refresh rate to 90hz and the electronic device 100 may render the picture frames at a frame rate of 90 PFS. Then, the electronic device 100 determines whether the frame rate of the electronic device 100 is stable.

If the frame rate of the electronic device 100 is unstable, the electronic device 100 reduces the refresh rate to 60hz again, and the rendering frame rate of the electronic device 100 is also reduced, and the electronic device 100 renders the screen frame at a frame rate of 60 PFS.

If the frame rate of the electronic device 100 is still stable, the electronic device 100 may increase the refresh rate to 120hz, and the electronic device 100 may render the frame at a frame rate of 120 PFS. Then, the electronic device 100 determines whether the frame rate of the electronic device 100 is stable.

If the frame rate of the electronic device 100 is unstable, the electronic device 100 reduces the refresh rate to 90hz again, and the rendering frame rate of the electronic device 100 is also reduced, and the electronic device 100 renders the frame at a frame rate of 90 PFS.

If the frame rate of the electronic device 100 is still stable, the electronic device 100 may render the frame at a frame rate of 120hz and refresh the display frame at a refresh rate of 120 hz.

Here, reference may be made to the foregoing description for specific implementation of how the electronic device 100 determines that the frame rate is stable or the frame rate is jittered, which is not repeated herein.

In this way, the electronic device 100 can dynamically adjust the refresh rate of the electronic device 100 according to the jitter of the frame rate and the stable condition of the frame rate, so as to avoid the influence of the jitter of the frame rate on the game experience of the user, and improve the game experience of the user.

In other possible implementations, the electronic device 100 may also directly boost the refresh rate to a maximum value.

For example, after the electronic device 100 reduces the refresh rate to 60hz, the frame rate of the electronic device 100 has stabilized. The electronic device 100 may directly increase the refresh rate to 120hz and the electronic device 100 may render the picture frames at a frame rate of 120 PFS. Then, the electronic device 100 determines whether the frame rate of the electronic device 100 is stable.

If the frame rate of the electronic device 100 is unstable, the electronic device 100 reduces the refresh rate to 90hz again, and the rendering frame rate of the electronic device 100 is also reduced, and the electronic device 100 renders the frame at a frame rate of 90 PFS. Then, the electronic device 100 determines whether the frame rate of the electronic device 100 is stable.

If the frame rate of the electronic device 100 is still stable, the electronic device 100 may render the frame at a frame rate of 90hz and refresh the display frame at a refresh rate of 90 hz.

3. Adjusting refresh rate based on game information

In some embodiments, the first gaming application may receive a frame rate (which may be referred to as a set frame rate) of a user-operated device game play scene, and the game information may be the set frame rate. The game information may also include other information such as a highest frame rate limited by the first game application, etc., the present application is described with respect to the game information including a set frame rate.

Fig. 6 shows a schematic diagram of an electronic device 100 rendering and displaying a picture frame.

As shown in fig. 6, the first game application may be an application that provides a game. The first game application can acquire the image resources of the picture frames, render the picture frames based on the image resources of the picture frames, and store the rendered picture frames in the buffer. And then, a buffer queue is arranged in the surface eFlinger to store the picture frames to be synthesized, the surface eFlinger can acquire the rendered picture frames from the buffer and synthesize the picture frames, and the synthesized picture frames are refreshed and displayed on a screen.

For example, if the electronic device 100 sets the refresh rate to 60hz, if the first gaming application and the surfeflinger side default to 4 buffers in common, the time period of the vsync signal is 16.6ms, that is, the first gaming application renders a frame of pictures every about 16.6ms and deposits it in the buffers. When surfeflinger occupies 2 buffers to compose and send out a frame of a picture, the first gaming application leaves 2 buffers to render the frame of the picture. When the refresh rate is 60hz and the rendering frame rate of the first game application is also stabilized at 60PFS, the time period of the vsync signal is 16.6ms, the first game application renders one frame of picture frame every about 16.6ms and stores it in the buffer, and the surfeflinger reads the picture frame from the buffer and synthesizes and sends the picture frame at about 16.6 ms.

When the first gaming application receives a user operation, the rendering frame rate will be set, e.g., raised, to 120PFS.

For example, when the electronic device 100 acquires the setting frame rate of 120PFS reported by the first game application, the electronic device 100 may set the refresh rate to 120hz or more.

In other embodiments, the first gaming application does not report the set frame rate to the system, and the electronic device 100 cannot obtain the set frame rate, whether surfeflinger is to obtain the frame from the buffer at 60hz and compose and send the frame. The first game application can store the rendered new picture frame in the idle buffer only after waiting for the SurfaceFlinger to acquire the picture frame from the buffer. In this case, the rendering frame rate of the first game application is also substantially unchanged, or maintained at around 60PFS, with the refresh rate unchanged. Even if the frame rate is set to 120PFS, the rendering frame rate of the first game application does not break through 60PFS, and the user experience is poor.

Fig. 7 shows a schematic diagram of another electronic device 100 rendering and displaying a picture frame.

As shown in fig. 7, in order to identify the buffer framing feature, in the game scenario, the first game application may apply for several buffers in addition, for example, apply for 4 buffers in addition, and under normal circumstances, the first game application may set the 4 buffers applied for in addition to a pending (to be activated) state. When the first game application receives a user operation to increase the frame rate, the first game application may set 4 buffers in a to-be-activated state to an active (activated) state. The first gaming application may render and store the picture frames based on 6 buffers. Therefore, the first game application can obtain the picture frames from the buffer without waiting for the surface eFlinger to release the buffer, so that the speed of the first game application for rendering the picture frames is increased, and the rendering frame rate of the first game application is increased.

Thus, the electronic device 100 may count the rendering frame rates of 6 buffers, and obtain the set frame rate. After the set frame rate is obtained, the electronic device 100 may increase the refresh rate such that the value of the adjusted refresh rate is greater than or equal to the set frame rate, such that the first gaming application may reach the user-selected set frame rate.

In other embodiments, as can be seen from the embodiment of fig. 6, if the surface efliger occupies two buffers, one buffer occupied by the surface efliger may be released, so that the surface efliger occupies only one buffer, and thus, the first game application may render and store the frame based on 7 buffers. Therefore, the first game application can obtain the picture frames from the buffer without waiting for the surface eFlinger to release the buffer, so that the speed of the first game application for rendering the picture frames is increased, and the rendering frame rate of the first game application is increased.

Thus, the electronic device 100 may count the rendering frame rates of 7 buffers, and obtain the set frame rate. After the set frame rate is obtained, the electronic device 100 may increase the refresh rate such that the value of the adjusted refresh rate is greater than or equal to the set frame rate, such that the first gaming application may reach the user-selected set frame rate.

The first game application may apply for 4 buffers to be activated when the first game application is started, and the first game application may also apply for 4 buffers to be activated when receiving the user operation to increase the frame rate, which is not limited in this application.

The first game application may apply for more or fewer buffers, which is not limited to applying for 4 buffers.

In this manner, the electronic device 100 may dynamically adjust the refresh rate based on the set frame rate in the first gaming application such that the first gaming application may render the resulting picture frames at a higher rendering frame rate.

4. Adjusting refresh rate based on game mode

The first gaming application may provide different gaming modes and the electronic device 100 may determine the resulting refresh rate based on the different gaming modes in the first gaming application.

By way of example, the first gaming application may provide a number of different gaming modes, such as a performance mode, an equalization mode, a power saving mode, and the like. Different game modes have different refresh rates based on rendering frame rate matching.

For example, for performance mode, where the electronic device 100 prioritizes game performance, such as user experience priority such as game smoothness, the electronic device 100 may determine a refresh rate that is twice the rendering frame rate based on the rendering frame rate, and the maximum refresh rate of the refresh rates that is twice the rendering frame rate is the refresh rate in performance mode. If there is no refresh rate twice the rendering frame rate, the one refresh rate with the largest value is selected.

Illustratively, if the rendering frame rate of the first gaming application is 30PFS, the supported refresh rates of the electronic device 100 include 30hz, 60hz, 90hz, 120hz, etc. Then the electronic device 100 may determine that the refresh rate is 120hz.

Illustratively, if the rendering frame rate of the first gaming application is 60PFS, the supported refresh rates of the electronic device 100 include 30hz, 60hz, 90hz, 120hz, etc. Then the electronic device 100 may determine that the refresh rate is 120hz.

Illustratively, if the rendering frame rate of the first gaming application is 90PFS, the supported refresh rates of the electronic device 100 include 30hz, 60hz, 90hz, 120hz, etc. Then the electronic device 100 may determine that the refresh rate is 120hz. If there is no refresh rate twice the rendering frame rate, the refresh rate with the largest value is selected.

For another example, for the balanced mode, the electronic device 100 needs to comprehensively consider the game performance and the game power consumption, and then the electronic device 100 may determine a refresh rate twice the rendering frame rate based on the rendering frame rate, and set the minimum refresh rate of the refresh rates twice the rendering frame rate as the refresh rate in the performance mode. If there is no refresh rate twice the rendering frame rate, then the one refresh rate closest to the refresh rate twice the rendering frame rate is selected.

Illustratively, if the rendering frame rate of the first gaming application is 30PFS, the supported refresh rates of the electronic device 100 include 30hz, 60hz, 90hz, 120hz, etc. Then the electronic device 100 may determine that the refresh rate is 60hz.

Illustratively, if the rendering frame rate of the first gaming application is 80PFS, the supported refresh rates of the electronic device 100 include 30hz, 60hz, 90hz, 120hz, etc. Then the electronic device 100 may determine that the refresh rate is 80hz. If there is no refresh rate twice the rendering frame rate, then the one refresh rate closest to the refresh rate twice the rendering frame rate is selected.

For another example, for the power saving mode, the electronic device 100 only needs to consider game power consumption, and the electronic device 100 may determine the value of the refresh rate based on the value of the rendering frame rate of the first game application, where the value of the refresh rate is the same as the value of the rendering frame rate, so that the power consumption of the electronic device 100 is the lowest, and the electric quantity of the electronic device 100 may be saved. If there is no refresh rate that is the same as the value of the rendering frame rate, then the one that is closest to the value of the rendering frame rate is selected.

Illustratively, if the rendering frame rate of the first gaming application is 60PFS, the supported refresh rates of the electronic device 100 include 30hz, 60hz, 90hz, 120hz, etc. Then the electronic device 100 may determine that the refresh rate is 60hz.

Illustratively, if the rendering frame rate of the first gaming application is 30PFS, the supported refresh rates of the electronic device 100 include 30hz, 60hz, 90hz, 120hz, etc. Then the electronic device 100 may determine that the refresh rate is 30hz.

Not limited to the performance mode, the equalization mode, and the power saving mode, the first gaming application may also provide other more gaming modes, which are not limited in this regard.

5. Adjusting refresh rate based on temperature information

The electronic device 100 may monitor the device temperature in real time. After the device temperature is greater than the preset temperature, the electronic device 100 may reduce the refresh rate, so as to reduce power consumption of the device, reduce the device temperature, and avoid the occurrence of the situation that the electronic device 100 is scalded.

In one possible implementation, the electronic device 100 may reduce the refresh rate to a minimum.

Illustratively, if the current year refresh rate of electronic device 100 is 120hz, the supported refresh rates of electronic device 100 include 30hz, 60hz, 90hz, 120hz, and the like. After the device temperature is greater than the preset temperature, then the electronic device 100 may determine that the refresh rate is 30hz.

In other possible implementations, the electronic device 100 may also reduce the refresh rate to one gear.

For example, if the refresh rate of the electronic device 100 is 120hz in the current year, the supported refresh rates of the electronic device 100 include 30hz, 60hz, 90hz, 120hz, etc. after the device temperature is greater than the preset temperature, the electronic device 100 may determine that the refresh rate is 90hz.

Optionally, after the electronic device 100 decreases the refresh rate, the electronic device 100 may also increase the refresh rate of the electronic device 100 after monitoring that the device temperature is less than the preset temperature. The electronic device 100 may gradually increase the refresh rate of the electronic device 100, or the electronic device 100 may directly increase the refresh rate of the electronic device 100 to a maximum value, which is not limited in this application.

6. Adjusting refresh rate based on frame insertion information

The frame insertion can increase one frame in every two frames of images displayed by the original images, shorten the display time between each frame, doubly improve the time, and generally improve the refresh rate of the screen, for example, the refresh rate can be improved from original 60Hz to 120HZ. Thus, the load of the mobile phone GPU for rendering the picture frames in different modes can be reduced.

If the user starts the frame insertion function in the first game application, the electronic device 100 may obtain the frame insertion value, and the electronic device 100 needs to adjust the value of the refresh rate to be greater than or equal to the frame insertion value.

Illustratively, the user selected plug frame is 120HZ, and then the electronic device 100 needs to adjust the refresh rate to at least 120HZ.

7. Adjusting refresh rate based on split-screen display of a game

If the game interface is displayed in a split screen manner, the power consumption of the electronic device 100 will increase, and in order to reduce the power consumption of the electronic device 100, the electronic device 100 may reduce the refresh rate.

Illustratively, if the current year refresh rate of electronic device 100 is 120hz, the supported refresh rates of electronic device 100 include 30hz, 60hz, 90hz, 120hz, and the like. After the game interface split screen display, then the electronic device 100 may determine that the refresh rate is 30hz.

Illustratively, if the current year refresh rate of electronic device 100 is 120hz, the supported refresh rates of electronic device 100 include 30hz, 60hz, 90hz, 120hz, and the like. After the game interface split screen display, then the electronic device 100 may determine that the refresh rate is 90hz.

Optionally, after the electronic device 100 decreases the refresh rate, the electronic device 100 may also increase the refresh rate of the electronic device 100 after the game is not split-screen displayed. The electronic device 100 may gradually increase the refresh rate of the electronic device 100, or the electronic device 100 may directly increase the refresh rate of the electronic device 100 to a maximum value, which is not limited in this application.

8. Adjusting refresh rate based on user operation

In some embodiments, the electronic device 100 may also receive a user operation to turn up the refresh rate of the electronic device 100. The electronic device 100 may adjust the refresh rate of the electronic device 100 to a user-selected refresh rate.

In some embodiments, the user operation may also be referred to as a user setting a refresh rate.

Illustratively, if the current year refresh rate of electronic device 100 is 90hz, the supported refresh rates of electronic device 100 include 30hz, 60hz, 90hz, 120hz, and the like. After electronic device 100 receives a user setting the refresh rate to 120hz, electronic device 100 may determine that the refresh rate is 120hz.

The above provides several different ways of adjusting the screen refresh rate. For example, electronic device 100 may determine a refresh rate based on a game scene, electronic device 100 may determine a refresh rate based on a rendering frame rate dithering scene, electronic device 100 may adjust a refresh rate based on game information, electronic device 100 may adjust a refresh rate based on a game mode, electronic device 100 may adjust a refresh rate based on temperature information, electronic device 100 may adjust a refresh rate based on an interpolation frame information, electronic device 100 may adjust a refresh rate based on a game split screen display, and electronic device 100 may adjust a refresh rate based on a user operation.

In some embodiments, the electronic device 100 may adjust the refresh rate based on the above-mentioned different scenes alone, and in other embodiments, the electronic device 100 may also adjust the refresh rate by comprehensively considering the combined actions of two or more scenes, which is not limited in this application.

The present application next describes the electronic device 100 determining the refresh rate by considering a plurality of factors, such as game scene, rendered frame rate dithering scene, game information, game mode, temperature information, frame inserting information, game split screen display, user operation, and the like.

/>

Table 1 shows the number of weight votes for different factors affecting the refresh rate. The game scene factor determines that the weighted ticket number of the refresh rate is 2 tickets. The rendering frame rate dithering scene factor determines that the weighted ticket number of the refresh rate is 1 ticket. The game information factor determines that the weighted ticket number of the refresh rate is 4 tickets. The balance mode factor determines that the weight ticket number of the refresh rate is 3 tickets, and the performance mode and power saving mode factors determine that the weight ticket number of the refresh rate is 2 tickets. The temperature information factor determines that the weighted ticket number of the refresh rate is 5 tickets. The frame inserting information factor determines that the weight ticket number of the refresh rate is 4 tickets. The game split screen display factors determine that the weighted ticket number of the refresh rate is 2 tickets. The user operation factor determines that the weighted ticket number of the refresh rate is 1 ticket.

For example, the refresh rate supported by the electronic device 100 includes 30hz, 60hz, 90hz, 120hz, etc., the counted number of tickets for the refresh rate of 30hz by the electronic device 100 is 3 tickets, the counted number of tickets for the refresh rate of 60hz by the electronic device 100 is 0 ticket, the counted number of tickets for the refresh rate of 90hz by the electronic device 100 is 9 tickets, the counted number of tickets for the refresh rate of 120hz by the electronic device 100 is 4 tickets, and the electronic device 100 can determine that the final refresh rate is 90hz. The electronic device 100 may refresh the display frames at a refresh rate of 90hz.

The value of the weight ticket number of each factor is only used to explain the present application, and the value of the weight ticket number of each factor may be other values, which is not limited in the present application.

Fig. 8 illustrates a schematic diagram of an electronic device 100 determining a refresh rate based on a combination of factors.

Exemplary refresh rates supported by electronic device 100 include 30hz, 60hz, 90hz, 120hz, and the like.

For example, as shown in FIG. 8, if the first gaming application enters a game play scenario, the electronic device 100 may increase the refresh rate, e.g., determine that the refresh rate is 120hz. Then the game scenario factor may cast 2 tickets to a refresh rate of 120hz.

Illustratively, as shown in FIG. 8, the electronic device 100 recognizes the frame rate jitter, and the electronic device 100 may decrease the refresh rate, e.g., determine that the refresh rate is 90hz. Then the render frame rate dither scene factor may cast a 1 ticket to a refresh rate of 90hz.

For example, as shown in fig. 8, when the electronic device 100 recognizes game information (e.g., a set frame rate), the electronic device 100 may set a value of the refresh rate to be equal to or greater than the set frame rate, e.g., set the frame rate to 120PFS, and may determine that the refresh rate is 120hz. Then the game information factor may cast 4 tickets to a refresh rate of 120hz.

For example, as shown in FIG. 8, the electronic device 100 may recognize a gaming mode (e.g., a performance mode) and the electronic device 100 may increase the refresh rate, e.g., determine that the refresh rate is 120hz. Then the play mode factor may cast 2 tickets to a refresh rate of 120hz.

For example, as shown in fig. 8, the electronic device 100 recognizes that the device temperature is greater than the preset value, the electronic device 100 may decrease the refresh rate, for example, determine that the refresh rate is 30hz. Then the temperature information factor may cast 5 tickets to a refresh rate of 30hz.

Illustratively, as shown in fig. 8, the electronic device 100 recognizes that the frame rate of the inserted frame is 120PFS, the electronic device 100 may set the value of the refresh rate to be equal to or greater than the value of the frame rate of the inserted frame, e.g., the electronic device 100 may determine that the refresh rate is 120hz. Then the framing information factor may cast 4 tickets to a refresh rate of 120hz.

For example, as shown in FIG. 8, electronic device 100 may recognize that the game interface is split-screen displayed and electronic device 100 may decrease the refresh rate, e.g., determine that the refresh rate is 90hz. Then the game split display factor may cast 2 tickets to a refresh rate of 90hz.

Illustratively, as shown in FIG. 8, the electronic device 100 recognizes the user operation and adjusts the refresh rate to 120hz, and the electronic device 100 may adjust the refresh rate to 120hz. Then the user operational factor may cast a 1 ticket to a refresh rate of 120hz.

Thereafter, the electronic device 100 may count the number of tickets for each refresh rate, and use the refresh rate with the largest number of tickets as the refresh rate finally determined by the electronic device 100.

As an example, as shown in fig. 8, the electronic device 100 determines that the ticket number of the refresh rate of 30hz is 5 tickets, the electronic device 100 determines that the ticket number of the refresh rate of 60hz is 0 ticket, the electronic device 100 determines that the ticket number of the refresh rate of 90hz is 3 ticket, the electronic device 100 determines that the ticket number of the refresh rate of 120hz is 13 ticket, then finally, the electronic device 100 determines that the optimal refresh rate is 120hz, and adjusts the refresh rate of the electronic device 100 to 120hz. The electronic device 100 may refresh the display frames at a refresh rate of 120hz.

It should be noted that, the embodiment of fig. 8 is merely an example for illustrating how the factors cooperate to determine the optimal refresh rate, and the factors cooperate to determine that the optimal refresh rate is different in different situations, which is not limited in this application.
